Title: Rotary Actuator Device
Inventor: STARY GARY M
IPC: F16K31/163
Filed: 1992-04-21
Abstract: A pressure controlled actuator mechanism (10) is disclosed for imparting rotary control motion to devices, such as valves, having rotary control means. The actuator includes a free-floating piston (20) movably and concentrically disposed within an airtight cylindrical housing (16). A non-rotating receptacle (36), having helically spiralled recesses therein, is attached therein to a support member (30) that is adapted to move in response to the free-floating piston (20). A rotatable shaft (42), one end of which mates with the helically spiralled recesses of the receptacle, is attached at its other end to a device having a rotary control means. A downward stroke of the receptacle rotates the shaft and activates the device. The support member (30) is spring biased to return the free-floating piston (20) to a starting position. In an alternative embodiment, the free-floating piston (20) is movably and concentrically attached to the support member (30) for travel therewith.  In this embodiment, a second pressure medium is introduced into the housing to cause the piston and support member to return to a starting position.

Title: Process and device for measuring the thickness of printing products, such as newspapers, periodicals and parts thereof
Inventor: STAUBER HANS-ULRICH
IPC: G01B11/06
Filed: 1994-10-19
Abstract: PROCESS AND DEVICE FOR MEASURING THE    THICKNESS OF PRINTED PRODUCTS              Abstract Of The Disclosure The thickness of a printed product resting on a support is measured by a scanning unit which has two sensing elements which can be pressed back against the force of a spring.  In a measuring zone, one sensing element is situated on the support and the other sensing element is situated on the printed product.  By means of two laser sensors, the length of the distance between the one laser sensor and a measuring face of the first sensing element is measured and the length of the distance between the other laser sensor and a measuring face of the second sensing element is measured.  From the difference between the lengths of these two distances, the thickness of the printed product can be determined.  By a comparison of this thickness actual value with a prescribed thickness set value, it can then be established whether the product measured is complete or whether pages, parts, or supplements are missing or whether the product has too many pages, parts, or supplements.

Patent CA-2125751-A1 (CA)
Inventor: BARNARD CHRIS
IPC: G02F1/31
Filed: 1994-06-13
Abstract: In an optical fibre system, an optical fibre is monitored to determine if a transmitted signal is being received at a receiving end. A bi-modal optical switch located between the laser transmitter and receiver operates in a first transmitting mode to allow a transmitted signal to pass through and in a second reflecting mode to reflect back the transmitted signal to the transmitting end. A monitor at the transmitting end monitors the fibre for the absence or presence of the reflected signal. The switch can be used to remotely monitor the receiver in an optical fibre link, to control handshaking between two computers, to remove idle sections from an optical fibre communications network, and to control the reflectance of a laser mirror.

IPC: C07C213/08
Filed: 1994-03-17
Abstract: A process for producing N,N-disubstituted aminophenol which comprises the steps of: obtaining a reaction mixture containing N-substituted aminophenol by reacting a dihydric phenol and an amine; subjecting said reaction mixture to heat treatment so as to thermally decompose quaternary ammonia salt contained in said reaction mixture into a dihydric phenol and an amine, and removing at least said amine by distillation; separating high-boiling impurities by distillation to separate N-substituted aminophenol; and subjecting said separated N-substituted aminophenol to reduction alkylation using an aldehyde compound.      According to the present invention, high-purity N,N-disubstituted aminophenol can be obtained in a high yield at high selectivity, and a reduction catalyst can be used repeatedly because its activity can be maintained at a high level and yet it can retain high activity for a long period of time.

Patent CA-2149414-A1 (CA)
Inventor: COTE PIERRE LUCIEN
IPC: B01D63/02
Filed: 1993-11-15
Abstract: A frameless array unconfined in a modular shell, proves to be a surprisingly effective membrane device for withdrawing permeate from a substrate, the flux through the membranes reaching an essentially constant relatively high value because of the critical deployment of fibers of the array as a skein, arching in a buoyantly swayable generally parabolic configuration within the substrate, above at least one of the array's headers in which the terminal end portions of the fibers are potted. The length of each fiber must be greater than the direct center-to-center distance between the array's pair of headers. For use in a large reservoir, an assembly of the array and a gas distributor means has fibers preferably >0.5 meter long, which together provide a surface area > 10 m2. The terminal end portions of fibers in each header are substantially free from fiber-to-fiber contact. When used in a tank from which the permeate is withdrawn at a location low enough to overcome the transmembrane pressure differential of the fibers, the permeate is withdrawn under a vacuum induced by gravity. To increase flux, a pump may be used which provides a suction less than 75 cm of Hg. When used in combination with a gas-distribution manifold disposed beneath the skein so as to flow bubbles through it, the surfaces of the fibers are surprisingly resistant to being fouled by build-up of deposits of inanimate particles or microorganisms in the substrate. Membranes with high transmembrane pressure differential may be used, if desired, and permeate removed with a vacuum pump.

Title: Programmable lighting control system with normalized dimming for different light sources
Inventor: FERENCE JONATHAN H
IPC: H05B37/02
Filed: 1994-10-04
Abstract: A lighting control system including a switching means connected between an AC power source and any of a plurality of different types of light sources. The switching means is operable in either an ON or OFF state to selectively apply power to a light source selected from a plurality of different types of light sources. A switch control means controls the operating state of the switching means, and includes means responsive to changes in a dimming control signal for adjusting the phase angle at which said switching means changes its ON/OFF state during each half-cycle of an AC waveform produced by the AC power source. Thereby, the power applied to said light source is adjustable between a minimum and maximum level. The phase angle is within a range which difers for each light source type in order to adjust the light output for each light source type between maximum and minimum levels. A display means displays instantaneous light level of a light source controlled by the system over a predetermined range of values. A normalizing means normalizes the system performance for different types of light sources so that said display displays the instantaneous light level for all of said different types of light sources over the same predetermined range of values.
